In the present disclosure, glossiness of the outersurface 20A of the toilet seat device 20 means glossiness of a surfacethat is easily seen from an upper side, a front side, a right side, anda left side when the toilet lid 50 is closed. The glossiness of theouter surface 20A of the toilet seat device 20 is also referred to asfirst glossiness. The glossiness of the outer surface 11A of the toiletbody 11 means glossiness of a surface that is not covered with theclosed toilet lid 50 and is easily seen from a front side, a right side,and a left side. The glossiness of the outer surface 11A of the toiletbody 11 is also referred to as second glossiness. The outer surface 20Aof the toilet seat device 20 includes an outer surface of the toiletseat box 30 and an outer surface of the toilet lid 50. The outer surfaceof the toilet seat box 30 is a top surface, a front surface, a rearsurface, a left surface, and a right surface of the upper cover 34, anda surface of the lower cover 33 that is not covered with the upper cover34 among a front surface, a rear surface, a left surface, and a rightsurface of the lower cover 33. The outer surface of the toilet lid 50 isa top surface and an outer peripheral surface of the toilet lid 50 in astate where the toilet lid 50 is closed. Hereinafter, the surfacelocated opposite the outer surface of the toilet lid 50 is referred toas the under-side surface 50A of the toilet lid 50. The outer surface11A of the toilet body 11 is an outer peripheral surface of theperipheral wall 14.

In the toilet seat device 20, glossiness of the outer surface of thetoilet seat 40 is also equal to or less than glossiness of the outersurface 11A of the toilet body 11. The outer surface of the toilet seat40 is a top surface, an outer peripheral surface, an inner peripheralsurface, and a lower surface of the toilet seat 40 in a state where thetoilet seat 40 is closed. In the toilet 10, similarly to the outersurface 20A of the toilet seat device 20, glossiness of the outersurface of the side cover 15 is also equal to or less than glossiness ofthe outer surface 11A of the toilet body 11.

In the present disclosure, a state in which the glossiness is equal toor less includes a case where the glossiness of the outer surface 20A isequal to the glossiness of the outer surface 11A and a case where theglossiness of the outer surface 20A is lower than the glossiness of theouter surface 11A. The state in which the glossiness is equal means thatthe difference between the glossiness of the outer surface 20A and theglossiness of the outer surface 11A is within ±10 and preferably within±5 when measured by a glossiness measurement method to be describedlater. That is, in the present disclosure, the glossiness of the outersurface 20A of the toilet seat device 20 is equal to or less than avalue obtained by adding 10 to the glossiness of the outer surface 11Aof the toilet body 11 and preferably equal to or less than a valueobtained by adding 5 to the glossiness of the outer surface 11A of thetoilet body 11 when measured by a method of measuring glossiness to bedescribed later.

The glossiness is measured as 60° specular glossiness by a gloss meteraccording to JIS-Z8741. As a gloss meter, for example, the gloss meter(GM-268A, manufactured by KONICA MINOLTA, INC.) can be used. Theglossiness of the outer surface 20A of the toilet seat device 20 ismeasured at one location of each of a flat region on the outer surfaceof the toilet seat box 30 and a flat region on the outer surface of thetoilet lid 50. The glossiness of the outer surface 11A of the toiletbody 11 is measured at one location of a flat region on the outerperipheral surface of the peripheral wall 14. When both the glossinessof the outer surface of the toilet seat box 30 and the glossiness of theouter surface of the toilet lid 50 are equal to or less than theglossiness of the outer peripheral surface of peripheral wall 14, it isdetermined that the glossiness of the outer surface 20A of the toiletseat device 20 is equal to or less than the glossiness of the outersurface 11A of the toilet body 11.

The glossiness of the outer surface 20A of the toilet seat device 20 andthe glossiness of the outer surface 11A of the toilet body 11 are 50 orless. The glossiness of the outer surface 11A of the toilet body 11 ispreferably 10 or more and 50 or less, more preferably 15 or more and 45or less, and still more preferably 20 or more and 40 or less. When theglossiness of the outer surface 11A of the toilet body 11 is within theabove range, it is easy to manufacture the toilet body 11 with lowgloss. The glossiness of the outer surface 20A of the toilet seat device20 is preferably 5 or more and 40 or less, more preferably 8 or more and35 or less, and still more preferably 10 or more and 30 or less. Whenthe glossiness of the outer surface 20A of the toilet seat device 20 iswithin the above range, it is easy to adjust the glossiness according tothe glossiness of the toilet body 11.

The glossiness of the outer surface 20A of the toilet seat device 20 ispreferably less than the glossiness of the outer surface 11A of thetoilet body 11. According to this configuration, even when illuminationlight and natural light strikes from above in the installed state of thetoilet 10, the luster of the toilet seat device 20 with respect to thetoilet body 11 is suppressed, and the appearance of the toilet 10 as awhole can be harmonized.

As illustrated in FIGS. 4 to 7, the toilet seat device 20 has a coatedsurface and a non-coated surface. In FIGS. 4 and 5, the coated surfaceis shaded, and the non-coated surface is drawn in a white outlinedshape. In FIGS. 7 and 8, the coating film 29 is schematically drawn by athick solid line.

The outer surface 20A of the toilet seat device 20 is a coated surface.That is, the outer surface 20A of the toilet seat device 20 is a surfaceon which the coating film 29 is formed by applying coating material to abase material 28. In the present disclosure, the outer surface 20A beinga coated surface means that a surface, of the outer surface 20A, that iseasily seen from an upper side, a front side, a right side, and a leftside is a coated surface. That is, it can be said that the outer surface20A is a coated surface as long as at least the easily visible surfaceof the outer surface 20A is a coated surface, and the surface that isnot easily visible may not be coated. The base material 28 is made of asynthetic resin and is colored in the same color as the coating film 29.In the coating film 29, a transparent coating layer is laminated on acolor layer in white or the like. In the non-coated surface, the basematerial 28 is exposed. The glossiness of the coating film 29 is lowerthan the glossiness of the base material 28. That is, the outer surface20A of the toilet seat device 20 is adjusted to have glossiness equal toor less than glossiness of the outer surface 11A of the ceramic toiletbody 11 by forming the coating film 29 on the base material 28. Theouter surface of the toilet seat 40 is also a coated surface in whichthe coating film 29 is formed by applying coating material to the basematerial 28. The outer surface of the side cover 15 is also a coatedsurface similar to the outer surface 20A of the toilet seat device 20.

As illustrated in FIGS. 4 and 6, the sliding surfaces 31A and 31B onwhich the toilet seat shaft portion 46 slides and the sliding surface31C on which the toilet lid shaft portion 55 slides are non-coatedsurfaces. That is, on the left surface of the toilet seat box 30, thecoating film 29 is not formed on the opening edge and the innerperipheral surface of the toilet seat support portion 24 and the outersurface of the toilet lid support portion 27. Around the sliding surface31B, the non-coated surface is provided in a range wider than a range inwhich the flange portion 47 of the toilet seat shaft portion 46 slides.The non-coated surface provided on the sliding surface 31A and on andaround the sliding surfaces 31B are hidden by the toilet seat 40, andare provided in a range that is hardly visually recognized by the userwhen viewed from the side. The non-coated surface provided on thesliding surface 31C is hidden by the toilet lid 50 and is provided in arange that is hardly visually recognized by the user when viewed fromthe side. In the toilet seat box 30 illustrated in FIG. 3, the innerperipheral surfaces 36A and 37A with which the toilet seat driving unit23 and the toilet lid driving unit 26 are in contact are non-coatedsurfaces. As illustrated in FIG. 7, in the toilet seat 40, the contactsurface 42A, of the rear leg portion 42, which comes into contact withthe toilet body 11 is a non-coated surface. As illustrated in FIGS. 6and 7, the under-side surface 50A of the toilet lid 50 is a non-coatedsurface. In the toilet seat box 30, the under-side surface of uppercover 34 and the under-side surface of lower cover 33 are non-coatedsurfaces.

Functions and effects of the embodiments configured as described abovewill be described.

The toilet seat device 20 of some embodiments is disposed on an upperpart of the toilet body 11. The glossiness of an outer surface 20A ofthe toilet seat device 20 is equal to or less than the glossiness of anouter surface 11A of the toilet body 11. Since the toilet seat device isdisposed on the upper part of the toilet body 11, the toilet seat deviceis more likely to receive illumination light and natural light than thetoilet body 11, and the gloss is easily felt by the user. When theglossiness of the outer surface of the toilet seat device is remarkablyhigher than the glossiness of the outer surface 11A of the toilet body11, there is a concern that the sense of unity of the toilet may beimpaired due to the strong luster of the toilet seat device. In thetoilet seat device 20, since the glossiness of the outer surface 20A ofthe toilet seat device 20 is equal to or less than the glossiness of theouter surface 11A of the toilet body 11, the luster of the toilet seatdevice 20 is suppressed, and toilet 10 exhibits a unified appearance.Therefore, according to the toilet seat device 20, the appearance of thetoilet 10 as a whole can be harmonized.

In some embodiments, the glossiness of the outer surface 20A and theglossiness of the outer surface of the toilet body 11 are 50 or less.According to this configuration, the appearance in which the luster ofthe toilet 10 is suppressed as a whole can be obtained.

In some embodiments, the outer surface 20A is a coated surface.According to this configuration, the glossiness of the outer surface 20Acan be easily adjusted by coating. For this reason, for example, theglossiness of the outer surface 20A can be appropriately set inaccordance with the toilet body 11 made of ceramics different inmaterial from the toilet seat device 20.

The toilet seat device 20 of some embodiments includes the toilet seatshaft portion 46 and the toilet lid shaft portion 55 which are movablyprovided. The sliding surfaces 31A, 31B, and 31C on which the toiletseat shaft portion 46 and the toilet lid shaft portion 55 slide arenon-coated surfaces. According to this configuration, there is noconcern that the coating films on the sliding surfaces 31A, 31B, and 31Care peeled off by sliding of the toilet seat shaft portion 46 and thetoilet lid shaft portion 55. For this reason, the design of the toilet10 is hardly impaired due to peeling and peeling residue of the coatingfilm. Furthermore, it is possible to suppress deterioration of thedimensional accuracy of the sliding surfaces 31A, 31B, and 31C due tothe film thickness of the coating film, which may impair the slidabilityof the toilet seat shaft portion 46 and the toilet lid shaft portion 55.

The toilet seat device 20 of some embodiments includes a toilet seathaving the rear leg portions 42. The contact surface 42A, of the rearleg portion 42, which comes into contact with the toilet body 11 is anon-coated surface. According to this configuration, there is no concernthat the coating film on the contact surface 42A is peeled off due tocontact of the contact surface 42A with the toilet body 11 orapplication of the weight of the seated person to the contact surface42A when the seated person sits on the toilet seat 40. For this reason,the design of the toilet 10 is hardly impaired due to peeling andpeeling residue of the coating film.

The toilet seat device 20 of some embodiments includes the toilet lid 50rotatably attached to the toilet seat box 30. The under-side surface 50Aof the toilet lid 50 is a non-coated surface. According to thisconfiguration, the area of the coated surface can be reduced tocontribute to cost reduction as compared with the configuration in whichthe under-side surface 50A of the toilet lid 50 is coated. In theconfiguration in which the upper-side surface of the toilet lid 50 is acoated surface and the under-side surface 50A is a non-coated surface,the boundary between the coated surface and the non-coated surface canbe disposed near the end surface of the toilet lid 50. For this reason,the boundary between the coated surface and the non-coated surface ishardly visually recognized by the user, and the design property of thetoilet lid 50 is hardly impaired due to formation of the coating film29. In the configuration in which the upper-side surface of the toiletlid 50 is a coated surface and the under-side surface 50A is anon-coated surface, coating can be easily performed separating thecoated surface from the non-coated surface.

The present disclosure is not limited to the embodiments described withreference to the above description and drawings, and for example, thefollowing embodiments are also included in the technical scope of thepresent disclosure.

The outer surface of the toilet seat device need only include a surfacethat can be easily seen from an upper side, a front side, a right side,and a left side when the toilet lid is closed.
